> Seeing what your AWS resources are actually doing.

## Metrics

**CloudWatch metrics** are numeric time-series data — CPU usage, request count, latency — automatically collected from most AWS services, viewable as graphs.

## Logs

**CloudWatch Logs** collects text output from your applications (Lambda, EC2, ECS) into a central, searchable place — instead of SSHing into every server to read a file.

## The car dashboard

Metrics are like a car's dashboard gauges — speed, fuel, temperature at a glance. Logs are the trip's black box — the detailed record you dig into after something goes wrong.
